Curry returned after missing two games with a sprained right ankle, but did not play in the second half after spraining his right knee.

Note: A source with knowledge of the situation has told The Associated Press that Byron Scott will not return to coach the Los Angeles Lakers next season. The person spoke on condition of anonymity Sunday night because the team hadn't announced Scott's firing yet. Scott coached the Lakers for the two worst seasons in franchise history, going 38-126. The Lakers finished with the NBA's second-worst record this season at 17-65. The Lakers are looking for their fifth head coach since Phil Jackson left in 2011. Yahoo Sports first reported Scott's firing.
